1:4

Step-by-step explanation:

so we are comparing the arc lengths to get the ratio of DE:BC

$\beta \div 360 \times 2 \times \pi \times r$

to get arc length BC as

$\beta \times \pi \times r \div 90$

and for DE as

$\beta \times \pi \times r \div 360$

so divide DE by BC where beta pi r will cancel out. and you remain with 1/4 Wich will translate to 1:4
